Question

One pico-coulomb (pC) equals:

Options

• \(10^{-9}\ \text{C}\)

• \(10^{-3}\ \text{C}\)

• \(10^{-6}\ \text{C}\)

• \(10^{-12}\ \text{C}\)

Answer 1

The pico-coulomb is the smallest practical sub-unit listed: \(1\ \text{pC} = 10^{-12}\ \text{C}\). It is smaller than the nano-coulomb (\(10^{-9}\ \text{C}\)) and the micro-coulomb (\(10^{-6}\ \text{C}\)).
